ATTACHMENT FOR HEADERS AND HEADER-BINDERS.

Specification of Letters Patent. Patented Dec, 25, 1917.

Application led November 20, 1915. Serial No. 62,518.

.vide mechanism of the character specified capableof being attached to existing machinery of the harvester type, as, for instance, headers andheader binders, for connecting the wheels of the harvester to a motor, to thus transform the harvester into a self-propelled machine.

In the drawings:

Figure 1 isa partial top plan view of the transmission mechanism in connection withl a grain heading machine or a binding header, where ,designed for propulsion by use of horse power; and v l Figs. 2 and 3 are sections on the lines 2--2 and 3 3, respectively, of Fig. 1, each looking in the direction of the arrows adjacent to the line.

In the present embodiment of the'invention, the main axle 1 of the machine is provided at each end with a propelling wheel 2, 2a, the said wheels being journaled on the ends of the axle, and each wheel 2 and 2a has secured to the inner face thereof and coaxial therewith a sprocket wheel 3 and 3, respectively, the sprocket wheels being rigid with the propelling wheels. v

Each of the sprocket wheels 3 and 3a is connected to a similar sprocket wheel 4 and 4, respectively,` in rear of the respective wheels 2 and 2, by lmeans of sprocket i chain 5 and i2-respectively.

The sprocket wheels 4 and 4a are secured to countershafts 6 and 6, respectively, and each of the countershats 6 and 6B is jonrnaled at its inner end in a bearing 7 on a substantially rectangular frame 8 arranged in rear of the axle 7.

The outer end of each countershaft is supf ported by a bearing 9 on the upper end of an upright or. standard 10 to be later described. Each of the said countershafts is provided with a second sprocket wheel 11 adjacent to the bearing 7 The sprocket wheels 11 of the counterdisconnecti'n shafts 6 and 6a are connected by sprocket I chains 12 with sprocket wheels 13 connect*- ed to a drive shaft, consisting of alined sec*-V tions 14 and 14a. These sections of the drive shaft are journaled in bearings 15 on the `frame 8 before'mentioned, and at their adjacent ends, the shaft sections are connected by a differential of usual construction (not shown) arranged within the differential casing 16.

A motor driven shaft 17 vis arranged at right angles to the drive shaft, the motor driven shaft beingA journaled in a bearing 18 on the frame 8, and the end of the said nected to the sections 14 and 14a of the drive shaft by the differential in the casing 16 in sections 14 and 14 will be driven, but the said' sections maymove angularly with re spect to each other, as in turning.

.The sprocket wheel 1 3 adjacent tothe propelling wheel 2 is secured to the shaft section 14,.but thesprocket wheel 13 adja` vcent to the propelling wheel 2a is secured tov a sleeve 14", which is journaled loosely on the shaft section 14 at the bearing 15.

The sleeve 14b and the shaft section 14 may be connected to rotate together, by

means ofl a clutch. The one .section 19 of `the clutch is rigid with the sleeve 14", while i the other section 20 of the clutch is feath-` ered on the shaft sectionilfl, asl indicated' jacent to the clutch, and is pivoted at 23 to a fixed support. l The arm 22 of the elbow lever has a fork,

An elbow lever consisting ofv armsv 22 and 24 extending at approximately a right angle .with respectto each other, is arranged adand the arms of the fork are provided with means for engaging 4an annular groove in lthe section 20.

A link 25 is connected with thel arm-24: i

of the elbow lever and suitable operating means (not shownl operate the is connected with thel link to move the same longitudinally to' clutch. When the. clutch sec-.f i

tions are connected as shown in Fig. 1, the.

supporting and propelling wheels 2 and 2l will be drlven to drlve the machine. When the sprocket whee1s13 'are disconnected by the clutch, the said lwheels will not be 'ven. Y

70 shaft adjacent to the drive shaft is con- The frame 8 before mentioned is supported by blocks 42 and sills 43, Which are mounted on elements 44 and 45 of the frame of the header-binder, and the sills 43 are connected to vthe element 44 by U-shaped clips 48.

rlhe hearings 9 before mentioned are in the uprights or standards 10 at the ends of a portion 50 of the frame, and inclined braces 49 extend rearwardly and dovvn-- Wardly from the upper ends of these standards to a connection With the frame.

The beam 45 is in effe-:t a sill beam With the axle and the frame, and the frame 8 is connected at the end and adjacent to this sill beam 45.

The propellin Wheels may be-driven from the motor7 Whic is supported at the rear of the frame, and Which drives the shaft 17, or the said Wheels may be disconnected from the motor and the shafts 26 and 27 connected therewith. Thus either the propelling Wheels or the operating mechanism, or both, may be connected with the motor.

n the ordinary header hinder, the supporting Wheels 2 and 2a not only support the apparatus, but they also drive the operating mechanism thereof; in the present in stance the supporting wheels have no driving connection with other units of the mechanism, but are simply propelled by the motnr.

The improvement may he attached to existing headers and header binders Without change in the binder or header, merely adding the sill and the parts supported thereby, namely, the frame 8 and connected elements.

I claim:

l. n combination, a frame, an axle, drive Wheels mounted on the ends of the axle, countershafts journaled parallel with the axle and having driving connection With the drive wheels, a sectional drive shaft arallel with the axle, a differential connecting the sections of the drive shaft, a motor shaft geared to the sectional drive shaft at the differential connection, a sprocket Wheel and chain connection between each section of the drive shaft and the adjacent countershaft, one of the said sections being loose on the drive shaft section, and a clutch for connecting a connection to a drive shaft section.

2. In combination, a frame, an axle, drive 55 Wheels mounted upon the ends of the axle, transversely arranged countershats having driving connections With the drive wheel. a sectional drive shaft having dit? i ,connection between the sections the sections connected with the res countershafts to be driven thereffv` shaft geared to the sectional dithe differential connection, and e tween the countershat and one ci ia shafts,
